I don't want to speak about why I left Chelsea. I will keep that to myself.
I have enjoyed my time at Chelsea and would like to thank the club and the fans for their support.
Of course, I know that I have some qualities. I think I can run a lot, that I'm physically well but if I have other qualities I will leave other people to speak about me.
It is sometimes better to stay with the same team... for stability.
When I arrived at Benfica I'd been playing like a No. 10 in the team, but the first thing the coach did was tell me: 'You are going to be a defensive midfielder here.'
I think derbies are really special because it's two local teams playing.
I think throughout your whole career a player can improve.
When you don't have results it is very difficult for players to have that high confidence.
I just have to improve here at Chelsea. I played in Portugal but here it is a higher level so I'm sure I can improve a lot and I will work hard every day.
I recognise fully why people wear poppies, I totally respect everyone's right to do so and I have total sympathy for anyone who has lost loved ones due to conflict.
As I said, when I played at Chelsea I give always my best to help the team but now Manchester United is my club and I will try to win there.
I'm happy to be working with Mourinho.
I am delighted to have joined Manchester United. To work with Jose Mourinho once again was an opportunity I couldn't turn down.
In the Champions League, everything is possible.
Vidic was a great player and one of the players where I look to be similar because he had a great career.
I have good friends at Chelsea. I talk sometimes with Eden Hazard, Gary Cahill, Cesc Fabregas but with all of them they are my good friends and they are good guys.
I had other offers, but Mourinho is Mourinho. It's exciting to work with him, he is the best coach in the world and I want to work with him for a long time.
I've played regularly in a big club at Benfica, where it is not easy and there is a lot of pressure. In those years I learned to be a winner and play under that pressure.
I always watch Chelsea games when I have the time and step-by -step, game-by-game, Chelsea is growing. I speak with Branislav Ivanovic, my friend and international team-mate a lot, a few times each month, so I know everything about the club.
